10.1 Reading Off Errors
If an error occurs, you can read off the error on the display or on the user interface of the
Sunny WebBox.
Reading off errors on the display
If an error occurs, the button glows red. The display shows the error number, wrench or telephone
receiver, and message in the text line. The error number is located in different positions on the display
depending on the error type. If you turn the switch to the left, the text line displays the corrective
measures for the error.
